What would happen if Robin didn't die at the end of season 5? (Zelena was never pregnant)

It was like an instinct to Regina. It was like she knew what Hades was going to do before he did it. As he was about to raise the crystal to start his attack, Regina used her magic to quickly disarm him. The crystal fell from his hand and Regina grabbed it and pointed it towards him.

"Now now, think about what you're going to do." Hades reasoned with his hands up.

"Do you honestly think you're going to get out of this after what you were about to do?" Regina asked him with a disbelieving look etched across her features.

"Regina, think about it. If you do this you're going to regret it." Robin whispered to her softly. Regina lowered the crystal, her eyes not leaving Hades. Just as Hades went to make a run for it, Zelena appeared in the doorway which was ultimately blocking his exit.

"Where do you think you're going?" Zelena demanded, anger clear on her face.

"They were going to take everything from us, I had to stop them." Hades tried to reason.

"I honestly through that you'd change with me in your life but it's clear you never will." In a green smoke Zelena had the crystal in her hand and then rammed it into Hades' chest. No one moved for several minutes after Hades turned into ash and then Zelena collapsed on the floor in a fit of tears. Regina walked over to her and gently pulled her into a hug telling her it was ok and that she did the right thing. The three of them walked out of the town hall slowly and headed towards Regina's car which was parked out front.

After Zelena was safetly at her house, Robin and Regina headed back to the mansion. When they arrived home they headed straight up to bed, both more tired than they realised. Regina went a changed in the bathroom whilst Robin changed in the bedroom and when Regina came out in her pyjamas they both got under the covers, facing each other.

"I thought I was going to lose you today." Robin whispered, his hand caressing her hip and tears brimming in his eyes.

"But you didn't and you never will." Regina promised, her hand tracing the outline of his face.

"I love you. I should have said this a while ago but I didn't and after what happened tonight I just needed you to know." Robin admitted.

"I love you too. I never thought it would be possible for me to love someone this much but here you are." Regina smiled, the smile she reserved only for him. He pulled her into a kiss, one that started of innocent but quickly got heated. Robin traced his tongue across the bottom of Regina's lips silently begging her to let him enter which she quickly agreed to. Whilst their tongues battled for dominance, Robin hovered above her with his hand caressing her thigh ever so lightly going over to ass.

"Robin... please.." Regina whimpered against his lips. Without a second telling, Robin hooked his fingers into her panties and pulled them down, throwing them across the room and Regina pulled his pyjama pants and boxers down, letting him free.

"I love you." Robin told her as he thrusted into her. The second he entered her, she felt complete. Robin started to speed up his thrusts which earned him some moans from his queen. Regina's hands wound their way into him hair, deepening the kiss even further if that was possible. As Robin's thrusts increase in speed, both of their climaxes were on the edge and with one last thrust both of them came over the edge, together.

"I love you." Regina moaned as she pulled Robin in for a kiss. Their kiss ended and Robin rolled off of Regina onto his back, pulling her to his side and he placed a kiss of her head. Regina's breathe evened out indicating to Robin that she has fallen asleep. After staring st her face for a couple of minutes, Robin placed a delicate kiss of Regina's lips and fell to sleep himself.
